Abstract
Water is prevented from entering the wall interior of a building from in and around a wall component, such as a window, mounted in the building wall, by positioning a diverter directly beneath the wall component. The diverter includes an upper surface that slopes toward the wall exterior, a plurality of spaced, parallel ribs extending upwardly from the upper surface and beyond the exterior wall to form a plurality of downwardly sloping channels, a cover over the outer ends of the ribs to form drainage openings at the ends of the channels, and filters in the channels to prevent water from entering the wall interior through the channels.
